31. Transformation, Ranking, and Clustering for Face Recognition Algorithm Performance
Stefan D Leigh, Nathanael A Heckert, Andrew L Rukhin, P Jonathon Phillips, Patrick J Grother, E M Newton, M Moody, K Kniskern, S Heath
The performance of face recognition algorithms is recently of increased interest, although to date empirical analyses of algorithms have been limited to rank-based scores such a cumulative match score and receiver operating characteristic. This pape ...
32. A Statistical Test Suite for Random and Pseudorandom Number Generators for Cryptographic Applications
Special Publication (NIST SP)
Andrew L Rukhin, Juan Soto, James R Nechvatal, Miles E. Smid, Elaine B Barker, Stefan D Leigh, M Levenson, M Vangel, D L. Banks, Nathanael A Heckert, James F Dray Jr, S C. Vo
This paper discusses some aspects of selecting and testing random and pseudorandom number generators. The outputs of such generators may be used in many cryptographic applications, such as the generation of key material. Generators suitable for use ...
33. Statistical Analysis of Partial Discharge Phenomena - Time of Occurrence Distributions
X. Han, Nathanael A Heckert, James J Filliben, Yicheng Wang
This paper presents time-of-occurrence (phase) distributions of individual pulsating partial discharges (PDs) which occur in a point-dielectric gap in air for ac voltage conditions. It is determined that the pulse phase distribution is adequately mo ...
